Vpliv glivnih in rastlinskih sekundarnih metabolitov na verižno reakcijo s polimerazo (PCR) = Effect of fungal and plant secondary metabolites on polimerase chain reaction (PCR)Thaler, Nejc ; Bajc, Marko, 1979-Sekundarni metaboliti so organske spojine, ki jih najdemo pri glivah in rastlinah, kjer imajo vlogo obrambnih in signalnih molekul ali zagotavljajo druge selekcijske prednosti, niso pa neposredno ... vpleteni v rast, razvoj in razmnoževanje organizma. Pri delu s tehnikami DNA so pogosto ravno sekundarni metaboliti tisti, ki posredno ali neposredno vplivajo na uspešnost verižne reakcije s polimerazo (PCR) ali reverezno transkriptazo, in sicer tako, da otežujejo celično lizo, povzročajo razpad nukleinskih kislin ali neposredno ovirajo delovanje encima polimeraze pri pomnoževanju tarčne DNK. Glavna ovira pri aplikaciji tehnike PCR v rutinski diagnostiki je priprava visoko kvalitetne DNA brez inhibitorjev. Še posebej to velja pri izolaciji DNA iz lesnatih rastlin (Minafra in sod., 1992) in vzorcev tal (Tsai in Olson, 1991). Večina standardnih postopkov izolacije nukleinskih kislin ne odstrani rastlinskih polisaharidov in polifenolnih komponent, ki imajo lahko neposreden vpliv na pomnoževanje s PCR (Demeke in Adams, 1992). Poskusi za premostitev tovrstnih ovir vključujejo bolj dovršene metode za izolacijo nukleinskih kislin in PCR, ki vključujejo uporabo pospeševalcev PCR za odstranitev ali zmanjšanje vpliva inhibitorjev PCR. Ta pregled je osredotočen na pristope za odstranitev ali zmanjšanje vplivov rastlinskih in glivnih sekundarnih metabolitov iz vzorcev tal, različnih rastlinskih tkiv in razkrojenega lesa zaradi pomena tovrstnih raziskav za gozdarstvo in lesarstvo.Source: Acta Silvae et Ligni. - ISSN 2335-3112 ([Št.] 100, 2013, str. 25-40)Type of material - article, component part ; adult, seriousPublish date - 2013Language - slovenianCOBISS.SI-ID - 3636646
